The water-soluble follicle stimulating substance, by some believed to originate in chorionic tissue, obtained from the serum of pregnant mares. It is used to supplement the action of estrogens.
A hormone that stimulates the testes and the ovaries to function.
Male reproductive hormone: (a) follicle-stimulating hormone (FSH), secreted by the anterior pituitary gland which stimulates the seminiferous tubules of the testes to produce sperm and also stimulates the ovary in the female; (b) interstitial-cell-stimulating hormone (ICSH), secreted by the anterior pituitary gland which stimulates interstitial cells around the seminiferous tubules to produce testosterone.
Hormones released by the pituitary gland that stimulate the gonads.
A hormone that produces a stimulatory effect on the gonads (ovaries and testes); primary gonadotropins include luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Hormone that stimulates the function of the gonads. The anterior pituitary gland secretes two gonadotropins: follicle-stimulating hormone and luteinizing hormone; during pregnancy the placenta secretes chononic gonadotropin, which helps to maintain the pregnancy. Also called gonadotrophin.
Any of several hormones synthesized and released by the pituitary gland that act on the testes or ovaries (gonads) to promote production of sex hormones and either sperm or ova. The main gonadotropins are follicle-stimulating hormone and luteinizing hormone. They may be given by injection to treat infertility.
